Still getting the same U0301 code and the same P062F; car dashboard info screen still telling me to "check transmission". Copied all tables and parameters from my old calibration file onto a brand new 2012 US CVT CRZ calibration file with the updated software. I did not drive the car around. Wouldn't think that would be necessary but I could try tomorrow.
What do we do now?

Would it help if I were to grab all the calibration IDs again to see if anything changed? Before updating to 3.0.9 and creating a new 2012 file, these were my IDs and the TCM didnt match:
ECM: 37805-RTW-A550
PCM: 37805-RTW-A550
TCM: 37806-RTW-3050

The A550 (2011) should be the right calibration for the ECU, not the 2012 A560.
But the 3050 in the TCM should be 2011 as well and work. I'll check again on Monday.
I suspect the bottom line is if you return to stock do you get the same code? If so, the dealer needs to flash the other modules to match.

Havent been able to go back to my original tune yet and looks at DTCs. Having some kind of issue with the Flashpro recognizing the VIN. I tried removing negative terminal for battery for 5 minutes, but maybe I should try longer. Will have my boyfriend (who does all my tuning stuff usually) look at it tomorrow.

Also, curiously, I cannot switch driving modes after changing my car to the 2012 calibration. May not be related, but it is odd. I am stuck in normal mode.

Hey guys I was having issues connecting to my ECU for a while - it was a separate issue that was causing the DLC (OBD II port) to lose power. Anyways, I was finally able to get this check engine light gone! Juan at Hondata rewrote the binary a while ago and it is in the latest Hondata Flashpro software update. He told me to start a new calibration file with this new software and copy over your tune info to the new file (charts, values etc).

Once I had the new and improved .fpcal file I flashed my ECU and all ECM/PCM and EEPROM error check engine lights are gone!

Some of you may still be having issues because updating your flashpro software is not enough. Update your software and then remake your tune in a brand new file. It takes a few minutes but luckily the Hondata software makes it very easy to copy paste the data charts and tables. Good luck!
